וּשְׁמַרְתֶּ֤ם אֶת־כָּל־חֻקֹּתַי֙ וְאֶת־כָּל־מִשְׁפָּטַ֔י וַעֲשִׂיתֶ֖ם אֹתָ֑ם וְלֹא־תָקִ֤יא אֶתְכֶם֙ הָאָ֔רֶץ אֲשֶׁ֨ר אֲנִ֜י מֵבִ֥יא אֶתְכֶ֛ם שָׁ֖מָּה לָשֶׁ֥בֶת בָּֽהּ׃
Ye shall therefore keep all My statutes, and all Mine ordinances, and do them, that the land, whither I bring you to dwell therein, vomit you not out.
